How to compare yarn needed for project

[FONT=“Comic Sans MS”][COLOR=“Red”]This is one of those things that kinna embarasses me that I don’t know,and should. How to figure out how much I’ll need for a project in some sort of simplified form. The last person I asked in person got out the calculator…eek! Being sort of math challenged,I need to learn this once and for all. Also…example: I want to buy some yarn for a pattern that calls for NORO KOCHORAN, I see some yarn that I think I like better called NORO SILK GARDEN. what do I need to do to find out if I can interchange?
As always…many thanks;) [/COLOR][/FONT]

Why should you know? It’s not like it’s some innate sense we all have, we all have to learn when we are new knitters. :thumbsup:

You need to know the yarn weight and gauge. If it’s only slightly different you might be able to get away with it by changing needle size, but you may need to do some math for some parts of it. These two yarns are very close in gauge so it’s probably fine.

Here’s a few websites that might help, too.

And while I’m at it another few that are good to bookmark. :wink:

Somewhere near the top of the pattern it will give you the guage - something like 20 stitches = 4". Usually it’s at 4", sometimes 1". Whatever it says, that’s your guage you need to match. It’ll also tell you what size needle to use, and also how how many rows per inch; those are not so important to match - mostly you need to match the guage, the stitches per inch.

Buy a ball of the yarn you want to use. Cast on 30 stitches or so and knit until your piece is 5" tall. Now get a ruler out and measure 4" across the center of the piecen & count the stitches in the 4". Do you match 20 sts in 4"? If so you are right on target to use that needle size and that yarn for your project.

If you didn’t match the given guage, switch needles to the next larger/smaller. Knit another 5". Measure again. Hopefully soon you will match the given guage of the pattern. Now feel how the knitting feels. Is it so tight that you hate it? too loose? If it has a good feel to it and you’d like the feel of your project with that ‘fabric’ then you are good to go.

As far as figuring out how much yarn you’ll need, once you’ve figured out if you can match gauge and the yarn will work for the pattern, look at the required skeins of yarn called for in the pattern. It should also give a yardage in the recommended yarn multiply that by how many skeins are called for. Look at the info on the wrapper for the yarn you want to substitute and divide the yardage into the total called for in the pattern yarn. That should give you a rough estimate and I would throw in an extra skein to be sure.
